Botulinum Toxin — Wrinkle Smoothing

Botulinum toxin injections at Berska Clinic are administered by MUDr. Šárka Běrská, who has delivered this treatment since 2008. By temporarily interrupting neuromuscular transmission in targeted facial muscles, botulinum toxin relaxes the repeated muscle contractions that cause dynamic wrinkles — forehead lines, glabellar frown lines, and crow's feet are the most common applications. The clinic also performs advanced applications including eyebrow lift, Foxy Eyes, V-shape face narrowing, Lip Flip, and Nefertiti lift (jawline-neck), as well as axillary, palmar, and plantar hyperhidrosis treatment. Effect duration is 4–6 months.

Botulinum toxin is one of the most studied and widely used aesthetic injectable agents in medical practice. At Berska Clinic, all botulinum toxin treatments are performed by MUDr. Šárka Běrská — not delegated to a non-physician operator. This physician-led approach ensures both the safety of injection technique and the precision of the aesthetic outcome. Mechanism: botulinum toxin type A works by blocking the release of acetylcholine at the neuromuscular junction, preventing the motor nerve from signalling the muscle to contract. The result is selective, temporary muscle relaxation. In aesthetic medicine, this is used to relax the muscles responsible for expression lines. The effect is not a numbing or filling of the skin — the mechanism is inhibition of movement, which allows the overlying skin to smooth and recover over the following 3–14 days as the toxin takes full effect. Standard treatment zones at Berska Clinic include: glabellar complex (frown lines between the brows), forehead horizontal lines, lateral canthal lines (crow's feet), eyebrow elevation (a small injection below the tail of the brow lifts it without weakening the forehead), and Foxy Eyes (a tail-of-brow/temporal lift effect). Advanced contouring applications include V-shape face narrowing via masseter reduction (reduces teeth grinding and softens a square jaw), Lip Flip (small injection into the orbicularis oris relaxes the upper lip border for a subtle pout without filler), and the Nefertiti lift (injections along the platysmal bands in the neck and along the jawline to sharpen the mandibular contour and reduce neck banding). Hyperhidrosis applications: botulinum toxin is a first-line medical treatment for primary focal hyperhidrosis — pathological excess sweating of the axillae (underarms), palms, or soles. MUDr. Běrská offers all three sites. The effect typically begins within 2–4 weeks and lasts 6–12 months for hyperhidrosis (longer duration than aesthetic applications). Onset and duration: aesthetic results are typically apparent within 3–7 days, with full effect at 14 days. Duration is 4–6 months for most facial applications, after which muscle activity gradually returns. Regular maintenance (two to three times per year) may reduce wrinkle recurrence over time. A two-week follow-up is standard practice to assess the result and apply any touch-up if needed.
